I had a good one once, it was about 6 weeks ago:
I was on this old boat (like 1700's wooden ship with sails etc.), and we were sailing by the coast, then a load of pirates on jet skis appeared and they started tossing Star Wars style thermal detonators at us. So I jumped of the boat and swam to shore, and I walked up the beach and into this forest, about 100m into the forest the was a road, and I was about to cross it, when a fox darted across the road, which shocked me a little, but as it ran across the road, a Ford Focus vapourised out of nowhere and ran the fox down. I starred at the remain for a minute, then crossed the road.
I found a path, and followed it out onto the cliff tops, where I could see my ship, burning, with huge holes in it, and the Jet-ski pirates celebrating and pulling tricks. All the crew were dead, I sat on the cliffs and stared out to sea. About 5 minutes or so later, a girl walked from the path out onto the cliff tops, and sat down next to me. We started talking fro a bit, and the after a while, she just randomly started hugging me and kissing me. By now I'd worked out it was a dream, because I've never had as girlfriend before (forever alone :-( ), but I was thinking, "Yeah, this is epic". Suddenly, this 5 year old girl popped out from behind the bushes and shouted "STOP BEING SOPPY!".
I woke up and thought "DAMMIT! I was enjoying that!"
It was really weird, because the jet ski stuff was all seemingly related to my friend, and the girl looked very similar to his girlfriend. Weird huh?
